自杀的人际关系理论（IPTS）在成年人中得到了广泛的研究，但在有自杀急性风险的青少年人群中却没有。因此，本研究旨在评估IPTS在自杀青少年住院患者高风险样本中的临床效用。我们评估了IPTS的结构（1）是否与精神病住院时的自杀想法和行为（STB）相关，（2）是否前瞻性预测出院后90天的自杀企图（SA）或精神病再住院。在入院时，青少年患者自我报告最近的STB，感知负担（PB），挫折感（TB）和抑郁症。父母在出院后90天报告了他们孩子的再次住院和自杀企图。广义线性回归模型被用来确定IPTS的关键结构是如何与入院前的STB，以及它们是否前瞻性地预测SA或出院后90天再住院。IPTS结构不能预测出院后90天内的再住院或SA。虽然PB和TB相互作用与住院前SI频率相关，PB、TB和NSSI相互作用与住院前SA相关，但这些相互作用的性质并不像IPTS预测的那样。IPTS结构是青少年住院前STB的相关近端预测因子，但可能与成人不同。
The interpersonal theory of suicide (IPTS) has been widely studied in adults, but not adolescent populations at acute risk for suicide. Accordingly, this study aimed to evaluate IPTS clinical utility in a high-risk sample of suicidal adolescent inpatients. We assessed whether constructs of the IPTS (1) are associated with suicidal thoughts and behaviors (STBs) on admission to a psychiatric hospitalization, and (2) prospectively predict suicide attempt (SA) or psychiatric rehospitalization 90 days after discharge. On admission, adolescent patients self-reported recent STBs, perceived burdensomeness (PB), thwarted belongingness (TB), and depression. Parents reported their child's rehospitalization and suicide attempts 90 days after discharge. Generalized linear regression modelling was used to determine how key constructs of the IPTS are associated with STBs prior to admission and whether they prospectively predict SA or rehospitalization 90 days after discharge. IPTS constructs did not predict rehospitalization or SA within 90 days of discharge. Although PB and TB interacted to associate with prehospitalization SI frequency, and PB, TB and NSSI interacted to associate with prehospitalization SA, the nature of these interactions were not as the IPTS predicts. IPTS constructs are relevant proximal predictors of prehospitalization STB in adolescents, but may operate differently than in adults.
